Congenital Deafness Treatment in Malaysia

What is Congenital Deafness?

Numerous reasons, such as genetic abnormalities, prenatal infections, and delivery difficulties, can result in congenital deafness, or hearing loss that is present at birth.
Types: Three categories of congenital hearing loss exist:

• Issues with the middle or outer ear are known as conductive hearing loss
• Problems with the inner ear or the nerves that connect the ear to the brain are known as sensorineural hearing loss
• Combining sensorineural and conductive hearing loss results in mixed hearing loss.

What is the Importance of Timely Treatment?

Children who receive early intervention are able to acquire language skills at a rate that is comparable to that of their hearing counterparts. Serious language and communication impairments may result from postponed treatment. Cognitive growth and hearing are intimately related. Better cognitive outcomes, such as enhanced academic performance and problem-solving abilities, are supported by early treatment.

What are the symptoms of Congenital Deafness?

• Hearing loss, including the incapacity to detect subtle noises
• Not reacting to sound
• Delay in young children's language and speech development
• Uncertain speaking
  

Causes and Risk Factors of Tethered Congenital Deafness

Causes:

• Genetic Factors: Genetic factors account for almost half of cases of congenital hearing loss. These may be X-linked, autosomal dominant, or autosomal recessive, among other inheritance types. Down syndrome, Usher syndrome, Treacher Collins syndrome, Crouzon syndrome, and Alport syndrome2 are a few genetic syndromes linked to hearing loss.
• Prenatal Infections: Congenital hearing loss may result from infections contracted during pregnancy, including toxoplasmosis, rubella, cytomegalovirus, and herpes simplex virus
• Birth complications include low birth weight, premature birth, birth trauma, and anoxia, or lack of oxygen during birth, all of which can cause hearing loss
• Maternal Health Conditions: The chance of congenital hearing loss might be raised by conditions such as maternal diabetes, high blood pressure (preeclampsia), and Rh factor issues.
  
  

Risk Factors:. A family history of hearing loss, facial abnormalities, ICU admission, history of meningitis, hearing loss-related syndromes, low Apgar scores at birth, medications known to cause hearing loss (such as aminoglycosides), elevated bilirubin, certain prenatal maternal infections, or suspicion of hearing loss are risk factors for congenital hearing loss.

Latest Research and Technologies in the Treatment of Congenital Deafness in Malaysia

National neonatal hearing tests have advanced the treatment of congenital deafness in Malaysia by facilitating early detection and intervention. Cochlear implants are the main surgical option for enhancing speech and academic performance, particularly when given early. Research is still ongoing, and Malaysia is keeping a careful eye on developments worldwide in gene therapies that address genetic causes of deafness, such as GJB2 mutations, for possible future adoption, even if bilateral implants are still restricted due to financing.

Congenital Deafness Prevention Tips

The majority of congenital deafness instances can be avoided by immunisation (rubella), awareness of the adverse effects (alcohol), or early treatment (T. gondii, hyperbilirubinemia), even if environmental causes account for 50% of occurrences.
